In 2015, the Asean single economic space will exist, opening up free movement for certain classes of workers across 10 very different Asian nations. At the end of 2015, the Millennium Development Goals (MDGs), the shared vision of the international community since 2000, will expire.
There can be no doubt that the MDGs have lifted millions out of chronic poverty, empowered women and granted greater access to education and health care. But we must now look at how development happens, and not dodge the complex question of migration.
Removing barriers to human mobility _ of which the Asean Economic Community (AEC) is a tentative first step _ continues the MDG momentum towards social equity. In that light, we contend that human mobility is crucial to prosperity and peace.
This tenet will be debated and tested at the UN General Assembly High Level Dialogue on Migration and Development in New York in October.
Closer in time and closer to home, this week in Bangkok the International Organisation for Migration (IOM) will play its part in shaping the post-2015 development landscape at the Asian preparatory meeting for that high-level dialogue.
We want to see migration in the post-2015 agenda, and we are convinced that the coming of age of Asean will advance prosperity and harmony in the region. We also believe that the AEC will move us, albeit cautiously, towards a global system of well-managed human mobility which protects migrants' rights, removes opportunities for human slave traders, and plans for the consequences and opportunities of migration. It will also move us towards a future where nations value the health of a citizen and a migrant equally as both an enabler and indicator of sustainable development.
Looking outside of Asean, we remind ourselves that one in seven people on the planet is a migrant. No one in our interconnected world can say their lives are not touched by migration, as billions more count on remittances to save them from poverty or move them up the developmental ladder. Furthermore, everything from the cars we drive to the chips in our mobile phones to the health care we enjoy has been designed, manufactured or delivered by a migrant somewhere along the line.
That is why we call migration a megatrend of the 21st century, and why we seek to stress that it is to be viewed as natural to the human condition: neither inherently bad nor inherently good but with the potential to do great things _ for economies, for individuals and for communities.
Even though they may feel pain, families make the choice to separate as they know it boosts their opportunities. In Bangladesh, just 13% of remittance-receiving households are below the poverty line, compared to 34% of those who get no money from abroad. In rural Pakistan, remittances mean higher school enrolment, particularly for girls. Evidence from other parts of Asia, from Latin America and from Africa points to the same result.
When we consider that remittance flows through official channels to developing countries topped US$448 billion in 2012 _ three times total aid flows from OECD donors in 2011 _ we can justifiably say that migration is the leading poverty reduction strategy in today's world. And that is even with tight regulations on migration.
Initial research shows that even a small increase in freedom of movement for migrants from developing countries could exceed combined global profits from eliminating remaining barriers to movement of goods and capital.
We also need to consider the effect of migration on strong but ageing economies. When we think of "greying populations", we tend to think of Western states, but increasingly, Asian countries, including China, are looking with concern at their demographics.
Migration is not only about moving to find work or to fill labour gaps. Migration will impact on development as environmental factors play a larger role. Indeed migration to cities, where half of us now live, means that 13% of the world's population now lives in low-elevation coastal zones, at risk of sea level rise as well as more frequent and stronger storms.
For all these reasons we believe it imperative that the next-generation development agenda include migration as part of the policy mix, and it must permeate whatever replaces the MDGs.
It is only on such a foundation that development initiatives can be built to release the development potential of migration, and the resources of migrant diasporas can find their full expression, beginning with benefits accruing to the migrants and their families.
Or, as UN Special Representative for Migration Peter Sutherland puts it: "Making migration part of the world's development strategy will have a meaningful impact on the lives of migrants, affording them greater access to rights and to the fruits of their labour.
"Perhaps even more important, it could change public perception of migrants, so they are viewed as a blessing rather than a scourge."
